3Medical Information
Medical Information
What the VPAP™ Auto Device is Intended for
The VPAPTM Auto is indicated for the treatment of obstructive sleep apnea (OSA)
in patients weighing more than 66 lb (30 kg). It is intended for use in the hospital
and home.
!
CAUTION (USA ONLY)
Federal law restricts this device to sale by or on the order of a physician.
Contraindications
Positive airway pressure therapy may be contraindicated in some patients with
the following pre-existing conditions:
•severe bullous lung disease
•pneumothorax
•pathologically low blood pressure
•dehydration
•cerebrospinal fluid leak, recent cranial surgery or trauma.
Warnings
•The entire manual should be read before using the VPAP Auto.
•Advice contained in this manual should not supersede instructions given by
the prescribing physician.
•A patient should not connect a device to the data communication port unless
instructed to do so by their health care provider or physician. Only ResMed
products are designed to be connected to the data communication port.
Connecting other devices could result in injury, or damage to the VPAP Auto
device.
•The VPAP Auto should only be used with masks (and connectors*)
recommended by ResMed, or by a physician or respiratory therapist. A mask
should not be used unless the VPAP Auto device is turned on and operating
properly. The vent hole or holes associated with the mask should never be
blocked.
Explanation: The VPAP Auto is intended to be used with special masks (or
connectors*) which have vent holes to allow continuous flow of air out of the
mask.
When the device is turned on and functioning properly, new air from the
device flushes the exhaled air out through the mask vent holes. However,
when the device is not operating, insufficient fresh air will be provided
* Ports may be incorporated into the mask or in connectors that are near the mask.

through the mask, and the exhaled air may be rebreathed. Rebreathing of
exhaled air for longer than several minutes can, in some circumstances, lead
to suffocation. This applies to most models of PAP devices.
•In the event of power failure or machine malfunction, remove the mask.
•The VPAP Auto can be set to deliver pressures up to 20 cm H2O. In the
unlikely event of certain fault conditions, pressures up to 30 cm H2O are
possible.
•If oxygen is used with this device, the oxygen flow must be turned off when
the device is not operating. If oxygen has been left on while the device is not
operating, disconnect the oxygen and wait 60 minutes before turning on the
device again.
Explanation: When the PAP device is not in operation and the oxygen flow is
left on, oxygen delivered into the ventilator tubing may accumulate within the
PAP machine enclosure and create a risk of fire. This applies to most types of
PAP machines.
•Oxygen supports combustion. Oxygen should not be used while you are
smoking or in the presence of an open flame.
•Always ensure airflow is being generated by the device before the oxygen
supply is turned on.
•Always turn the oxygen supply off before stopping the airflow from the
device.
Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen
concentration will vary, depending on where the oxygen is introduced, the
pressure settings, patient breathing pattern, mask selection and leak rate.
•Do not use the VPAP Auto if there are obvious external defects or
unexplained changes in performance.
•Do not open the VPAP Auto case. There are no user serviceable parts inside.
Repairs and internal servicing should only be performed by an authorized
service agent.
•Explosion hazard—do not use in the vicinity of flammable anesthetics.
Warnings Related to Treatment
•If you stop your PAP or bilevel treatment, your sleep apnea will return
immediately.
•Always consult your clinician if you expect to be in a situation where you
cannot use your VPAP Auto unit.
•If you are admitted to a hospital or prescribed any other form of medical
treatment, always inform the medical staff that you are being treated with
PAP or bilevel. It is also important to contact the clinician who is treating you
for sleep apnea.
•If you experience an infection of the upper respiratory tract, middle ear, or
sinuses, contact your clinician before continuing your PAP or bilevel
treatment. You may be advised to stop treatment until the infection has
cleared. If you continue with treatment during an infection, be sure to clean
your mask and tubing after every use.

5Medical Information
Cautions
•At low pressures, the flow through the exhalation ports of your mask may not
clear all exhaled gas from the tubing. Some rebreathing may occur.
•The airflow for breathing produced by this device can be as much as 11oF
(6oC) higher than the temperature of the room. Caution should be exercised if
the room temperature is warmer than 90oF (32oC).
•When AC mains power (100/240V AC) is not available, always use a ResMed
DC-12 converter. (The DC-12 converter is available as an optional accessory.)
•If supplied, the ResScan™ Data Card module is designed for use with
specific ResMed devices.
•Only use the ResSan Data Card module (if supplied) as specified in this
manual.
Note: The above are general warnings and cautions. Specific warnings,
cautions, and notes appear with the relevant instructions in the manual.
Adverse Effects
Patients should report unusual chest pain, severe headache or increased
breathlessness to their prescribing physician. An acute upper respiratory tract
infection may require temporary discontinuation of treatment.
The following side effects may arise during the course of therapy with the
device:
•drying of the nose, mouth or throat
•nosebleed
•bloating
•ear or sinus discomfort
•eye irritation
•skin rashes
•chest discomfort.
